Pattern revolved cut-extrude

[Raoul-RW]

Hello there,


I am workingon a solidrevolved extrude with a ( shape around an axis.Iadded a small revolved cut-extrude at this modeland now I want to pattern it upwards to make a ( shape with several cuts.


However, I didnt manage to make it work because I want the cut following the outer shape of the model and not just straight upwards. When I activate 'Geometry Pattern' SolidWorks doesnt want to make it work and replies with the error that the selected featurescouldnt be patterned.


How to model this amount of cuts without making a complexsketch? I am convinced that it should be possible with a pattern.I think I am just missing something very simple but cannot figure it out. Thank you in advance.

Can you post an image of the sketch that you want to pattern and the shape that you are trying to pattern it along?

Hello,


The first image shows the Sketch of the Revolved cut-extrude. The second image shows the way how I want that Revolved cut-extrude followingouter shape of the model.

I think that you need to make 4 separate cuts (at the for red levels) then use ALL this cuts in a PATTERN feature to finish your task.

Hope this is a help for you.

Good luck !

Raul,


I don't think the SW pattern features are capable of keeping that constant offset within a single pattern feature. Why don't you just pattern your lines within the sketch, and create all cuts with a single revolve cut? Another method (to keep it parametric) is to use surfaces... here's my stab at it:

There are only a few parameters related to the pattern of cuts: Initial location, width, &pattern pitch. I can even change my curved surface offset easily... Gawd I love surfaces!!!

I was able to remove one more feature, by putting the cut surfaces in the original sketch...

7parameters, 5 features, 1 sketch. Fully parametric &lean. Raoul, can you do it this way?

Sorry. I miss understood your problem.

I spent a lot of time in finding the answer and I see that usingthe good old surfaces are the solution. Thank you so much!
